That looks like the wheel just fell off, which would indicate that it MUST have been making a horrid noise for a while.

If my suspicions are correct and the machine in question has a Belarus badge on the front there is absolutely no way you could tell that was about to happen, any telltale noises or vibrations would be difficult if not impossible to feel or hear over all the other noises and vibrations that are factory fitted.

Looks like the axle just snapped, if that's the case, then there would be NO warning noises/vibrations at all.
When a vehicle looses the wheel nuts, then there is a horrible shuddering sensation for quite a while as the wheel starts to wobble, until the last nut/stud gives way.
No vision of the wheel wobbling at all, so that rules out the wheel nut's being lost, or the studs failing.

Doesn't look like there is any axle attached. That should be a full floating axle as well. Probably only held on with a couple of studs/nuts.

The video is blurry and can only be slowed by stopping it then advancing frame by frame but immediately before the wheel comes off there is evidence the backhoe made a slight bounce as if there were a small dip in the road. Not significant enough to cause impact loading by any means. Next when the wheel first comes off the tractor it looks like there is a short stub of the axle shaft. Backhoes of that size are generally based on AG tractors of the same series which in most cases the wheel rim bolts directly to the axle flange the axles are semi floating just like rear wheel drive cars and lighter duty pickups.
I own one of the largest wheeled backhoes that Ford/ New Holland ever made it weighs in at around 18,000 lbs with the same semi floating axles.
I agree with everyone else's analysis that if it were the lug nuts or studs failing there would have been a time lapse of noise and wobbling as it would be nearly impossible for all of them to simultaneously fail

Looks like a few inches of the axle still protruding from wheel centre, and casting a shadow in this frame's lower left corner:

Good eye DIYSwede!

Good call.
